High Street Charlottesville, VA 22902 (434) 227-5140 / keane@shimp-engineering.com RE: Comment Letter for SDP-2020-00018 (Brady Bushey Ford — Major Amendment); 3" Submittal Dear Mr. Rucker: The Planner for the Planning Services Division of the Albemarle County Department of Community Development will recommend approval of the plan referred to above when the following items have been satisfactorily addressed. (The following comments are those that have been identified at this time. Additional comments or conditions may be added or eliminated based on further review.) [Each comment is preceded by the applicable reference to the Albemarle County Code.] The original comments from the first review and action letter for SDP2020-00018 are in gray font. Follow-up comments from the review of the second submittal are in bolded black font. Please address these follow-up comments as well. Each comment is preceded by the applicable reference to Chapter 18 of the Albemarle County Code (Zoning Ordinance), unless otherwise specified. (The following comments are those that have been identified at this time; additional comments may be added or eliminated based on further review.) Review comments from the other reviewing divisions and agencies are also attached. Please submit ten (10) copies of the revised plan to the Community Development Department when revisions have been made. Please contact me at your earliest convenience if you have questions or require additional information or assistance. Sincerely, Andy Reitelbach Senior Planner / areitelbach@albemarle.org / (434)-296-5832 x 3261 1 Albemarle County Planning Services (Planner) — Andy Reitelbach, areitelbachgalbemarle.org — Requested Changes: 1. 130.6.3(a)2(b); SP1994-000041 This proposed project requires an amendment to special use permit SP1994- 00004, for outdoor storage, display, and sales uses in the Entrance Corridor. The changes proposed on TMP 78- 6 are not in general accord with the concept plan approved as part of SP1994-00004. An additional building is proposed for this parcel, along with new display spaces that are not shown on the approved plan. These changes will require an amendment to the special use permit. Because some of these proposed changes and display spaces cross onto TMP 78-7, it is recommended that a boundary line adjustment occur prior to the SP so that parcel 7 can remain separate and not be considered as a part of the special use permit. An SP is not required, per discussions with Zoning division. However, the 7 proposed new spaces labelled as "employee/service" spaces in the center -front of the property, between the two entrances, need to be removed, as they are not in compliance with the approved 1994 SP. Comment addressed. 2. [32.5.2(b); 32.5.2(n)] Revise the parking schedule on the cover sheet of the site plan and the labels on the plan sheets. a. The number of spaces added up between the two different uses listed in the parking schedule is 242; however, the total number of spaces said to be provided is 243. Comment has been addressed. b. Counting the number of spaces on sheet C4, there are more than 243 spaces provided, including the accessible spaces in front of the sales and service buildings on TMP 78-6, which do not appear to be included in the total of 243 when counting the full number of spaces. There are only 240 parking spaces labelled as being for customers/employees/service spaces, even though the cover sheet identifies there being 242 spaces. The discrepancy appears to be the small parking lot to the east of Building B. There are only 18 spaces depicted, even though the label says there are 20 employee/service spaces. Revise the cover sheet to state there are only 240 spaces, or add an additional 2 spaces in somewhere else. In addition, the row of "13" spaces north of Buildings B and C actually only has 12 spaces. 12 spaces would make sense with the overall label for that area identifying 34 spaces (12 + the 22 spaces directly south of the preserved steep slopes), so revise the "13" to a "12." It appears that there continues to be miscalculations in the number of parking spaces provided. On the cover sheet, it states that there are 225 spaces provided. However, 181+46=227 spaces, based on the numbers provided. In addition, counting the number of spaces depicted on sheet C4 that are not display spaces, I can only find 224 spaces. Part of the issue may be in the existing parking lot behind Building A2, there's a label for 56 spaces, but the individual numbers only add up to 55 (unless the one van accessible space by itself on the northwest side of the building is counted as a part of that 56, then then that subtotal works). However, there are still only 224 spaces depicted. c. This site cannot have more than 243 spaces, which is 20% more than the required amount. See comment Ile below. Comment addressed. d. Clearly label which spaces are for display, which are for employee parking, and which are for customer parking. Some areas are not clear. There are new areas of parking spaces on TMP 78-6 that are double - stacked. These spaces are not labelled as display. However, employee/customer parking spaces cannot be double -stacked. This comment has not been addressed. Spaces for employee/service parking cannot be double-parked. Areas of double -stacking that need to be revised include the two rows of 7 space each between the two front entrances to the site, and the 16 spaces in the parking lot east of Building B. Comment addressed. e. Identify the types of spaces in the "existing paved parking area" at the rear of TMP 78-7. Are these display, customer, storage, etc.? These spaces were not included in the overall parking count and could possibly increase the number of spaces on the site even more over the 243 maximum number permitted. This comment has not been addressed. What kind of parking is proposed here? Customer, display, service, storage, something else? Elaborate. Comment addressed. 3. [32.5.2(n); 4.12.13; 4.12.191 Provide the dimensions of the dumpster pads. The dumpster pad on TMP 78-7 appears to interfere with vehicular circulation. Revise the location. Screening of dumpster pads is required. Provide the screening materials proposed to be used and profile of the enclosure. Identity the height of the retaining wall around the dumpster pad. Comment addressed. 4. [32.5.2(n)] Railings or guard rails are required on the retaining walls. Show these rails. Is a handrail proposed for the retaining wall around the dumpster pad behind Building B? Comment addressed. 5. [32.5.2(n)] Depict the obstruction -free two-ft. overhang required for parking spaces that are 16 ft. in depth. Provide the 2-ft. overhang for the ten (10) spaces on the far eastern side of the property, adjacent to TMP 78-9. Comment addressed. 6. [32.5.2(n)] Provide the footprint square footage of the new sales wings on the enlarged building on TMP 78-7. The total proposed new square footage of the buildings as shown on the plan does not match that which is identified on the cover sheet. There is a difference of about 3,000 square feet. Clarify this discrepancy. Is the building in the back paved parking area of TMP 78-7 included within the square footage identified on the cover sheet? Comment addressed. 7. [32.7.2.31 Provide internal sidewalks or crosswalks on the site to connect the buildings and to connect the sidewalk along Route 250 with the enlarged sales building. Provide an accessible ramp for the sidewalk in front of the enlarged sales building. Accessible ramps need to be provided at all spots where the ends of sidewalks meet travelways, including between Buildings B and C, and in front of Building A. Also, the sidewalk referenced in the comment response letter connecting Route 250 to Building A does not appear to be depicted on the site plan. Show this connection. Accessible ramps need to be provided for the sidewalk leading from the front of Building B to the front of Building C. 8. [4.17; 32.7.8] Include footcandle measurements for the existing lights to demonstrate that the combination of the existing non -conforming lights with the proposed new lights does not increase the footcandle measurements above the permitted range, where the light from the poles would overlap. It appears that the existing lights are labelled as "D" on the lighting plan. Include this identification in the key on sheet C8. None of the fights on the photometric plan have the labels that are identified in the lighting schedule. The footnote indicates that the existing fights are labelled as "A"; however, none of the existing lights appear to have an "A" labelling them. Revise the labelling regimen. 9. 14.17; 32.7.8] There are several new light poles that appear to be placed on top of trees shown on the landscaping plan. These lights include the following: B-1, B-2, and B-12. Shift either the light poles or the trees. Light B-2 now appears to be located within the required 2-ft. overhang for the parking spaces. Revise the location of this light. Comment addressed. 10. [32.7.91 Identify the location(s) of the 14,102 sq. ft. of the required interior/parking lot landscaping, as well as the trees and shrubs used for this landscaping. The dotted hatch mentioned in the comment response letter does not appear on the landscape plan. Clarify where the interior/parking lot landscaping is proposed on the plan. If the "low maintenance ground cover" is the dotted hatch, these areas are not sufficient for the required landscaping and are in the wrong locations for this required landscaping. Comment addressed. 11. [32.7.91 Revise the "tree per 10 parking spaces" calculations, as the display spaces must be included as well. Provide the additional trees required once these spaces are included in the calculations. Revise this calculation to take into account the comments made in comment #11 above, so that staff can accurately review the required number of parking lot trees Comment addressed. 12. [32.7.91 The required amount of tree canopy is proposing to use a significant amount of existing tree canopy. Provide a conservation checklist in accordance with 32.7.9.4(b)2 in order to satisfy this requirement. Also, identify those trees and landscaped areas proposed to be preserved in order to meet this requirement. Comment has been partially addressed. Remove the plants that will not be at least 5 feet in height within 10 years from the canopy calculations. Comment addressed. 3 13. Identify what the battery area is and what is proposed there. Comment addressed. 14. Now that staff has a better understanding of where the proposed parking is and which parking spaces are proposed for each use, it has been determined that there is not enough parking on each of the two lots for them to be able to stand separately if the parcels were sold to different owners. A shared parking agreement will be required to be reviewed, approved, and recorded at the courthouse for these two properties before the site plan can be approved, ensuring that sufficient parking is provided for each use on each parcel. Comment has not been addressed. A shared parking agreement will be required prior to approval of the site plan. The shared parking agreement will need to be reviewed by County staff and recorded at the courthouse prior to approval. Please let me know if you would like an example of previously recorded shared parking agreements for reference. With the proposed closure of the entrance directly into TMP 78-6 from U.S. Route 250, a shared access easement will also need to be a part of this agreement to ensure continued access onto 78-6. It is recommended that these items be included with the easement plat required by Engineering for the stormwater management facilities and access easements; however, the various agreements and easements can be done with separate plats and deeds if so desired. Comments from Other Reviewin¢ Departments and A¢encies Albemarle County Architectural Review Board (ARB) Margaret Maliszewski, mmaliszewski@albemarle.org — Requested changes; see the comments below: 1. Indicate the location of the Porsche DC charge box on the plan. (If the location was already added to the plan with revision date of 11/30/20, please describe the location or highlight it on the plan.) Ensure that it is screened from view from the EC street. 2. The site plan now shows the entrance/exit on parcel 78-6 to be closed. The landscape plan still shows landscaping associated with the entrance/exit. Revise the landscape plan to show a consistent appearance along the EC frontage. 3. Provide documentation from ACSA that the proposed frontage landscaping is acceptable. 4. Comments on the Comprehensive Sign Plan and glass sample will be forwarded soon. Albemarle County Engineering Services (Engineer) John Anderson, janderson2galbemarle.org — Requested changes; see the attached memo. Albemarle County Service Authority (ACSA) Richard Nelson, melson@serviceauthority.org — Requested changes; see the comments below: Submit 3 copies of the utility plan for review and approval, now that there is a water main extension on site. Confirm if the existing metal building # 1290 is currently served by water. The presence of existing sewer indicates this may already be served by water. Provide fixture counts. Proposed landscape plan has plantings closer than 10 feet from the existing water main along 250. Include water main profile.

Recommend revise title to include ref, to project file number: SDP202000018. (Rev. 1) Addressed. 2. Provide deed bk.-pg, ref to interparcel access easements (Final Site Plan checklist, Easements, 0 item). (Rev. 1) Comment persists. Applicant (6/15/20 letter): `No interparcel access easements exist.' This appears inconsistent with SDP201800089, Final Site Development Plan for Pantops Comer (image below), [image removed with Rev. 2 review comments] which shows an interparcel 37' access easement. It seems there should be a corresponding easement on the Brady -Bushey parcel, unless easement operates in one direction only (it may), as easement that allows one-way travel from Brady -Bushey to Pantops Corner, but not travel in the reverse direction. In that instance (if this is an intentional, 1-way easement), comment will be withdrawn. (Rev. 2) Addressed. Applicant response (10/22/20 letter): `Yes, this access easement only operates in one direction —its function is to allow vehicle delivery trucks to enter the property. Those trucks (and customers/employees) will depart via Rte 250 entrance.' 3. Major site plan amendment approval requires an Approved VSMP /WPO plan. Please submit VMSP /WPO application at earliest convenience. (Rev. 1) May persist. Applicant: `Acknowledged. A VSMP plan has been submitted.' A quick county system (CV) search yields no match for Brady -Bushey Ford VSMP, but Engineering anticipates WPO plan submittal, per Applicant response. (Rev. 2) Addressed. WPO202000032 review is in process. 4. Include title sheet Note that preserved and managed steep slopes exist on parcels. (Rev. 1) Addressed. 5. VMSP /WPO plan approval requires permanent SWM facility easement plat recordation (for any on -site SWM facilities). (Rev. 1) May persist. Applicant: `Acknowledged. SWM easement is now shown on the plans and an easement plat will be recorded prior to approval.' As ollow-up: Please direct reviewer to sheet showing SWM easement for proposed dry detention pond. It appears an identifying label was cutoff on C4. (Rev. 2) Addressed. 6. Provide brief narrative of Stormwater Management on C 1. Consider stormwater quantity and quality in context of increased impervious area /post -developed land cover, 100-year floodplain, stream buffer, etc. (Rev. 1) Addressed, but as follow-up (please address via VSMP plan), please note that discharge to mapped floodplain meets flood protection portion of 9AVAC25-870-66.C, but design must also address channel protection (9AVAC25-870-66.B). Looking forward: C4 Engineering Review Comments Page 2 of 9 a. Relatively recent DEQ correspondence explains that energy balance applies at limits of analysis for discharge to natural conveyance. That is, simply discharging to a natural conveyance at limits of analysis is insufficient. Instead, at limits of analysis, discharge to natural conveyance requires demonstration that Qi-y, post -development meets the Energy balance equation requirement. (Rev. 2) Addressed via WPO202000032. Applicant: `Noted ... This condition has been met and is addressed in the VSMP plan WPO202000032.' b. Please revise label, 05, to read: `Conveyance will be designed to meet channel and flood protection requirements, see WPO plan' since this is where design will meet requirements, and where Albemarle County will evaluate design for channel and flood protection compliance. (Rev. 2) Addressed. c. Do not locate proposed SWM facility on preserved steep slopes since SWM facilities are not listed as a by -right use (18-30.7.4.b.1.). Applicant may apply for a special use permit to allow siting a SWM facility on preserved steep slopes —see 18-30.7.4.b.2. (Rev. 2) Addressed. Applicant: `The proposed SWM facility is outside of the preserved slopes. Following our correspondence on September 2, 2020, a note has been added to ensure no disturbance of preserved steep slopes during construction and maintenance.' 7. Evaluate drainage feature at north property boundary for perennial stream features. Include note on plans that perennial stream exists or does not exist on subject parcel. GIS stream buffer layer may be unreliable at this location. Provide date of field evaluation, and any field data. Ref. code 17-600.A. (Rev. 1) May persist. Applicant: `USGS maps categorize this stream as intermittent. This was field verified on May 21, 2020, by Justin Shimg P.E. No aquatic life was found in the stream. Stream bottom was rounded, rather than cut with deep grooves. Additionally, debris was blocking a portion of the stream which suggested that flows were not strong enough to clear out the debris. A note is now included on the plans near the stream location stating that it is intermittent and was field verified.' Note cannot be located. In this circumstance, a plan sheet reference would be very helpful. Please guide reviewer to sheet with note. (Rev. 2) Addressed. Applicant: `Note is located on C2, the note is located around property line L3-L4.' 8. Show and label preserved and managed steep slopes on C3, C4, C5. (Rev. 1) Partially addressed. As follow-up: Please label preserved and managed steep slopes on C3, C4, C5. (Rev. 2) Addressed. 9. Resolve WP02018-00088, Amendment 1 as prerequisite to SDP202000018 approval (email, this date). (Rev. 1) Addressed. Applicant: `Revised plans have been submitted and approved.' 10. Revise C3 consistent with actual existing conditions (image, below). Shimg Engineering should have access to designs for development on adjacent parcels to the west. Please rely on these, as well as satellite imagery ` 1 11 3 20 ifn ge b_1o... image removed with Rev. 1 comments Also, lease ref. g ry (__ __......_ _: g ) P Final Site Plan checklist for plan reviewers, Existing conditions plan view information, I` item: `accurate current existing topography at the time of submittal, including all existing features, and any recent disturbances.' (Rev. 1) Addressed. Applicant: `The existing conditions page has been updated to show the stockpiles that exist on site currently. Please note that the original topography (without stockpiles) is shown on other grading pages, as stockpiles will be moved at the beginning of construction and it is easier to see how the grading will tie in once the stockpiles are removed.' 11. Show pipes as well as storm MH /inlet structures on C4, or turn storm utility MH /inlet layer off. (Rev. 1) Addressed, 12. Revise loading zone east of existing service building, TMP 78-7, Lot 8, since not adjacent to the structure it serves and since it impedes parking spaces to north, and circulation, generally. Ref. 18-4.12.13.a.b. (Rev. 1) Addressed, 13. Provide autotum figure for dumpster pad. Use single -unit (SU) truck design vehicle. Ref. Fig. 1, VDOT Road Design Manual, Appendix B(1), 20-ft wheelbase. Include entering site, reverse maneuver, and exiting site. (Rev.1) Partially addressed. As follow-up: SU-30 does not align with dumpster. Operation requires forks on waste management vehicle to align closely with slots in dumpster, oblique alignment does not work. Ref, autotum fig., C 13. Provide design sufficient to allow proper operation. Note that in image below, vehicle strikes dumpster, dumpster enclosure, and grazes a curb with no appreciable clearance. Engineering Review Comments Page 3 of 9 (Rev. 2) Addressed. `The curbing in the area has been slightly revised. The dumpster location has also been revised and can now adequately accommodate truck movement. See updated autotum diagram on C 13.' 14. Provide field survey data that supports note that `portion of preserved slopes disturbed is less than 25%.' Engineering Div. has received no information that would exclude a portion of the steep slopes overlay district (preserved steep slopes) from limits against disturbance or development found at 18-30.3. (Rev. 1) Addressed. Applicant: `LIDAR data showed that the slopes we had previously proposed to be disturbed were less than 25%, however we have no way of submitting a certified survey now because approximately 3,000 CY dirt have been placed directly blocking those slopes. The site plan has been revised showing 4 less parking spaces in that area to allow for the retaining wall to remain outside of the preserved slopes district.' NE ] _. DI-3n Er M� �Ot" E%. MILS V `� 1}�� ¢�j NEW �I 15. Provide guardrail (VDOT GR-1 or GR-2) at top of4', 13' and 6' proposed retaining walls along northern edge of parking on TM 78-6, Lot 7. (Ref. Retaining Wall Plan checklist for plan reviewers, Plans, 2' item). (Rev. 1) Not addressed. Applicant: `Guardrail has been provided along the northem-most wall where a car would be traveling with potentially greater speed in the direction of the wall. The other walls are along parking spaces where cars would be either stopped or driving slowly, and we do not see the need for anything other than handrails in these locations.' Asfollow-up: Please revisit /consider review -comment exchange for Oak Hill Convenience Store, SDP201800082 (SE project): Engineering Review Comments Page 4 of 9 a. Extensive exchange (email /perhaps meetings) to discuss guardrail for parking spaces fronting retaining walls (Rev. 2) Addressed. Applicant: `Noted, we have provided guardrail along retaining walls near parking areas.' b. Exchange included Albemarle County Engineer who expressed not a preference but a requirement for this design circumstance. (Rev. 2) Addressed. Applicant: `Noted.' c. County Engineer affirmed rationale for guardrails for retaining walls next to parking (to prevent vehicles from (however unlikely) crossing a retaining wall, from which there is no immediate recovery) as structures that may help minimize risk of injury to persons, or damage to property. (Rev. 2) Addressed. Applicant: `Noted.' d. Final Site plan checklist for plan reviewers, p. 1 /last item: (Rev. 2) Addressed. Applicant: `... correct, retaining wall checklist dictates guardrails shall be installed with new retaining walls.' Retaining Wall Plans checklist. Any walls supporting roads or necessary infrastructure require engineered plans (not generic manufacturer's details) and computations. {Design Manual, section 81 This will also be required where walls are close to property lines and there is the danger of affecting neighboring property, either during construction, with later failures, or with pedestrian or vehicle safety. These concerns can be alleviate with layout spacing also. In any case, retaining walls will require building permits at construction. e. Retaining Wall checklist for plan reviewers, (Rev. 2) Addressed. Applicant: `...... correct, retaining wall checklist dictates guardrails shall be installed with new retaining walls.' Plans: safety railing shown for retaining walls over 4' high guardrail with VDOT designations or equivalent shown for retaining walls next to parking or travelways VDOT approval for any walls in right-of-way Accurate depiction of horizontal depth (batter) on site plans. All structural reinforcement, steal, or geogrids specified. All dimensions specified Constructability; there should be no vertical cuts on property lines during construction, such that abutting property does not become unstable. Adequate room for construction needs to be available. f. Given this, emphasizing that (county) Engineering position is unchanged (nor will it), please consider and respond to initial comment and provide guardrail at proposed 4' and 15' Max, height walls west of 18 parking spaces, and east of 13 parking spaces. These are not display spaces, but sections of a 54-parking space employee /service space parking lot. East of this parking lot are unrecoverable preserved steep slopes (beyond 15' Max, ht. wall); west of this parking lot are proposed 2:1 slopes (falling) to a 7' retaining wall on Pantops Corner parcel (4' Max. ht. wall). Ref. SDP201800089 /SE. C5; orange highlight, image below. Engineering withdraws request for GR-2 at 6' Max. ht. wall for 22 parking spaces, location shown in lower right of image below. [image removed with Rev. 2 review comments) (Rev. 2) Addressed. Applicant: `Walls have now been provided for 4' and 15' height walls where marked on image.' From SDP201800089. C5 [ image removed with Rev. 2 review comments ] g. New: Provide GR-2 at 18 display spaces, image, below. Existing slopes west of these 18 spaces are 0.5:1 (10' h, 20' v) with a series of tiered walls presenting —20' drop onto the adjacent parcel. 40' grade break over 25' horiz represents unacceptable risk (at present, without guardrail), and risk should Malloy convert display spaces to public use, or should parcel transfer or rezoning require transition from display to public use parking spaces. Engineering requests design revision, there may be an argument from a design or approval perspective, but only guardrail alleviates risk inherent at these now -unprotected display spaces, and at other locations shown with this major amendment. Please consider plan review checklists. Inadvertent risk presented by proposed design and recently -constructed offsite improvements are the basis of review comment request. (Rev. 2) Withdrawn. Applicant: `The existing slopes at west of that parking lot were shown Engineering Review Comments Page 5 of 9 based on a survey completed at time of offske retaining wall construction. Those slopes showed the cut required to install the walls along with backfill and geogrid. Currently, there is only a 4' vertical drop from the curb to the off -site walls. The top offsite wall is located about 13' from the back of the curb —so the existing slope adjacent to the parking lot is about a 30% grade (slightly flatter than a 3:1 slope.) So the biggest issue was that the topo that was shown is not representative of the current site conditions, and has now been fixed. Based on the VDOT GRIT manual, Figure 1 page 1-5, a guardrail is not warranted for 30% slopes. Since there is an existing 13' wide 30% slope adjacent to the parking lot, this should satisfy VDOT requirements. For additional consideration, if Engineering were to interpret that the retaining walls offsite add an additional 20' drop, there is no ordinance that requires an applicant to improve existing conditions based on an existing offsite retaining wall. We do agree that if the applicant builds a wall that requires guardrail, they have to provide that guardrail. However, the retaining wall checklist covers new construction —construction completed as part of the site work. In this case, the wall is simply an existing condition, albeit a recent one. Technically, the wall applicant should have built a guard rail for the wall, if a guard rail were required. So to summarize, I think the recoverable 30% slope does not require a GR at this location (based on VDOT chart), and even if that wall were to require a GR, the ordinance should have required the wall applicant provide that during wall construction. So for these reasons, we cannot find requirements for our client to install a guardrail above the existing offsite retaining wall at the western boundary near TNT 78- 5A.' As follow-up: • Request for guardrail is withdrawn. • Request for GR was made, but is now withdrawn. • Engineering recommends guardrail. • If no GR, Engineering recommends a low -profile block wall that may prevent a car inadvertently mounting curb, crossing the 13' strip, and possibly experiencing a 20' vertical drop. • A specific, unambiguous requirement may not exist in ordinance that requires applicant (SE client Malloy Ford) to install a guardrail above the existing offste retaining wall at the western boundary near TNT 78-5A. Malloy Ford may simply want to weigh the decision and minimize potential liability that attends design that forsakes protection beyond a modest concrete curb. • Engineering rejects the argument that a pre-existing off -site 20' high retaining wall forecloses site plan review request for GR on the Malloy Ford parcel. • Consider this example (though not the case here): Site A constructs a 20' retaining wall to develop Site A. This wall provides 20' vertical break to adjacent Site B, at higher elevation. Site B is undeveloped at time Site A application is approved. There is no indication that parking will be proposed in close proximity to the top of this newly - constructed retaining wall. As consequence, Engineering requests handrail for the retaining wall, but not guardrail. Later, Site B is developed. Site B proposes parking 13' from the top of the retaining wall /20' drop. Engineering requires GR adjacent to parking as a barrier to minimize risk that a vehicle may mount the curb, and within space available, be unable to halt progress across a strip between curb and wall. Engineering requests GR to protect Site B personnel, public, etc. In this example, Site A, developed first, is allowed to construct a 20' high wall without GR, since no indication Site B will in the future need GR to accompany unforeseen design /parking proximity. • This example highlights circumstance where GR is required later but not with initial wall. • Request for GR reflects reviewer's PE-credentialed approach that recognizes public welfare as a consummate principle (minimize risk), request for GR provides assurance that recognizes and helps protect this Applicant's interests, now and in the future. Intent is not argumentative, intent is conservative approach to design that recognizes risk, that seeks the best outcome. Engineering does not impose requirements where none exist, Engineering Review Comments Page 6 of 9 however finely drawn. Engineering (with GR comment) had hoped to engage on topic of safe, conservative design in the public and Applicant's interest. We now recommend a barrier behind existing concrete curb, to mitigate effects of unforeseen circumstance. The case here: Engineering, during review of Pantops Comer FSP, raised issue/s relating to retaining walls with Shimp Engineering (SE), then representing Pantops Corner. In comment response, above, SE draws a distinction between requirements then vs. now, stating `Technically, the wall applicant should have built a guard rail for the wall, if a guard rail were required.' We appreciate and would like to examine this response in light of SE response when issue of retaining walls /offsite easement (with Malloy Ford) was raised with SE by J. Anderson during review of Pantops Comer (SUB201900059) plat. Engineering did not request GR for the Pantops Comer retaining walls. It is unclear we would have ever requested GR. In all likelihood, we would not have since GR would have to be installed on adjacent parcel (Malloy Ford). Retaining wall design for Pantops Comer ran to the property line and left no room to install GR on Pantops Comer parcel (since wall locations critical to site development —hotel, Wawa, etc.). We cannot be certain, since we did not request GR with Pantops Corner development. What we do know is SE response when Engineering attempted to engage on topic of retaining wall /off -site easement requirements when reviewing Pantops Comer development. Please consider whether it is perhaps disingenuous to now state that Engineering should have committed to require GR for these retaining walls, given resistance when Engineering raised topic of easements (in 2019) tied to retaining walls to be constructed on Pantops Comer parcel. It is one thing to say Engineering should ensure requirements are met contemporaneous with development. It is another to say this while at the same time forcefully resisting Engineering overtures to do that —to identify or ensure valid ordinance requirements are met. Quotes below, from SE response to review comments, Pantops Comer easement plat (SUB201900059). o Applicant [SE] response: `Regardless of whether this is a current issue, you have brought up a site plan review item. This is an easement plat, so while this comment may be appreciated on the site plan (if indeed the County Attorney deemed it an issue), this should not be applicable to this easement plat.' o Applicant response: `The temporary grading easement on TMP 76-6, as shown on previously submitted site/road plans for Pantops Corner, was already recorded in DB4553 PG 473-486. This is not a proposed easement, nor is it onsite so therefore it will not be shown on this plat.' o Applicant response: `Plats are required to show all known easements on the subject property. These are known easements, recorded in the Albemarle courthouse in DB5147 PG 221, 228 & 229, therefore they will be shown. We would like to remind County Engineering that their review is for engineering items on this easement plat only. Please leave legal questions, such as debating whether a recorded item is an easement, to the County Attorney, who is the qualified professional in this matter. The existing easement will remain on the plat as it is required to be shown.' Again, Engineering did not request GR for Pantops Comer proposed retaining walls, either when reviewing Pantops Comer Final Site Plan (SDP201800089) or easement plat (SUB201900059). There was, however, a clear attempt to engage on topic of retaining walls and off -site grading easement (on Malloy Ford parcel), but SE appeared disinclined to engage on any but technical grounds, and Engineering relented, on both points. Engineering encourages Malloy Ford (SE client) to consider consequence that may arise should a vehicle, however unlikely, cross curb and retaining wall with a 20' vertical drop.

(Rev. 1) Partially addressed. As follow-up: Provide handrail label for retaining wall (Max. ht. =8') east of building B. (Rev. 1) Addressed. Engineering defers to VDOT on entrance requirements from Richmond Road, U.S. Rt. 250. (Rev. 1) Persists. Applicant: `Acknowledged. This is still being worked out with VDOT.' (Rev. 2) Addressed. Applicant: `Coordination with VDOT is ongoing. It is likely that VDOT will approve the current strategy (one full entrance with one right -in -only entrance).' Engineering recommends provide distance from proposed revised entrance to adjacent entrances, east and west (entrance 2, entrance 4, sheet C8). (Rev. 1) Addressed. Sidewalk at SE comer of new sales building (FEE 419.50) appears < 5' w. Ensure all sidewalks are 5' minimum width. (Rev. 1) Addressed. Applicant: `Sidewalk at the SE corner of the new sales building (now labeled Building A4) is 5 ft. the dimension is now shown. It does taper off to a smaller width, but it is used to facilitate vehicular circulation, not pedestrian circulation since there is no door in that location.' Label all sidewalk widths. (Rev. 1) Addressed. Label drive aisle width between curbing from entrance 2 to buildings that are interior to TM 78-6, Lot 7. (Rev. 2) Addressed. Provide CG-12 pedestrian ramps at each entrance: 2, 3, 4. (Rev. 1) Partially addressed. As follow - depict ramps as shown in CG-12 detail (radially /curved), see detail, CC 12 or, modem as needed if CG-12 does not offer precise depiction required to align ramps with pedestrian direction of travel. A visually impaired pedestrian may `read' detectable ramp surfaces to align travel (similar to reading braille, by touch). Note orientation of schematic representation of CG-12 ramps on C4. Note detail on C 12, From C4: Examine orientation /graphic depiction of every CG-12 adjacent to U.S. Rt. 250, some within Rt. 250 RW. Virtually all require revision to show orientations that align detectable surfaces with receiving ramps such that a visually impaired person does not stray into Rt. 250 by mistake. CG-12 design assists visually impaired and ambulatory impaired, alike. Other VDOT standards /devices alert when it is safe to enter a crosswalk; pavement markings and traffic signs alert motorists to the presence of pedestrians. All of it may be needed to protect pedestrians, especially in highspeed or high traffic volume locations. U.S. Rt. 250 presents both. CG-12 at this location is a critical design element; please show ramps in plan view, as they are intended to be built to safely direct any pedestrian from one ramp to the next. (Rev. 2) Addressed.

VSMP Plan should present details concerning adequate channel and flood protection. (Rev. 2) Addressed. WPO202000032 is under review. 32. Revise storm Al -A6 design. Every pipe in this run has velocity that exceeds (VDOT Drainage Manual 9.4.8.7.) 10 fps standard. (Rev. 1) Withdrawn. Review error. Applicant: `The referenced section is for concrete pipes. HDPE pipes are significantly more resistant to abrasion. The design standards manual states design velocities should be between 3 and 20 fps with a maximum pipe slope of o16%. All pipes meet these standards.' 9.4.8.7 Maximum Grades Slopes that incur uniform flow velocities in excess of 10 fps should be avoided because of the potential for abrasion. Slopes in excess of 16% are not preferred because of the need for anchor blocks. When anchor blocks are used, they should be installed at bvery other pipe joint, as a minimum. (See Special Design Drawing No. A-73 and MA- J3 for Anchor Details for Concrete Pipe) 33. Provide retaining wall safety railing detail. (Rev. 1) Addressed. 34. Provide LD-204, inlet design.
